长江三角洲区域部分省市危险废物跨省转移生态补偿机制的构建和分析

Construction and analysis of ecological compensation mechanisms for cross provincial transfer of hazardous waste in some provinces and cities in the Yangtze River Delta region

危险废物跨省转移生态补偿是落实生态文明战略的重要举措之一,可有效引导该过程中的生态受益者履行补偿义务,在保证省域环境公平的前提下促进危险废物利用处置行业高质量发展。本研究依托排污权有偿使用制度探索建立市场化危险废物跨省转移生态补偿机制,基于总成本修正模型,核算受偿区生态建设与保护总成本,并引入生态补偿系数、危险废物利用处置系数得出生态补偿资金计算修正公式。长江三角洲区域产生的危险废物具有产业覆盖广、废物结构多、跨省转移量大等特点,对于开展危险废物跨省转移生态补偿机制的研究具有代表性,因此选取了长江三角洲区域4个临近省作为模拟对象,举例计算危险废物跨省转移生态补偿金额,制定了可能的征缴流程。研究结论为危险废物跨省转移生态补偿机制探索与实践提供了新的理论依据,可作为推动经济社会可持续发展的有益补充。

The ecological compensation for the cross provincial transfer of hazardous waste(abbreviated as EC-method)is one of the important measures to implement the ecological civilization strategy.EC-method can effectively guide the ecological beneficiaries to fulfill their compensation obligations and promote the highquality development of the hazardous waste utilization/disposal industry while ensuring provincial environmental fairness.This study explored the establishment of a market-based ecological compensation mechanism for the cross-provincial transfer of hazardous waste,relying on the system of paid use of pollution discharge rights.Based on the total cost adjustment model,it calculated the total costs of ecological construction and protection in the compensation-receiving areas.Additionally,it introduced ecological compensation coefficients and hazardous waste utilization and disposal coefficients to derive the revised formula for calculating ecological compensation funds.Hazardous waste generated in the Yangtze River Delta region is characterized by broad industrial coverage,diverse waste structures,and substantial inter-provincial transfer volumes.This makes it a representative case for studying the ecological compensation mechanism for the crossprovincial transfer of hazardous waste.Therefore,four neighboring provinces within the Yangtze River Delta region were selected as the study subjects for simulation.Examples of the calculation of ecological compensation amounts for hazardous waste transfers between provinces were provided,and a potential collection process was established.The research conclusion provides a new theoretical basis for the exploration and practice of EC-method,which serves as a beneficial supplement to promoting sustainable economic and social development.
